Answer:

x = 36.9°

Step-by-step explanation:

We need to find out what sides of the triangle we have, so we can find the formula for the missing angle, x.

We have been given the opposite and hypotenuse so we are using sine

SOH, CAH, TOA

sin (x) = opp ÷ hyp

Substitute in the values

sin (x) = 9 ÷ 15

Simplify

sin (x) = 0.6

Rearrange to find x

x = sin^-1(0.6) - Type this into your calculator

sin^-1 is the inverse or opposite of sin

x = 36.8698... ≈ 36.9°

of the bill was for labor costs. How much was the total bill if the cost of the labor was $79.50? Let b = the amount of the total bill.

Which equation and solution is correct?
Five-thirds b = 79.50, and the total bill was $47.70.
Three-fifths (79.50) = b, and the total bill was $127.20.
Five-thirds b = 79.50, and the total bill was $212.00.
Three-fifths (b) = 79.50, and the total bill was $132.50.

Answers

Answer:

132.50

Step-by-step explanation:

3/5b = 79.50

b = (79.50) / (3/5)

b = 79.50 * 5/3

b = 397.50/3

b = 132.50

132.50 is the total bill

Which of the following is equivalent to –(4 + (–7))?
–4 + 7

–4 + (–7)

4 + (–7)

–4 – (–7)

Answers

Answer:

-4+7, -4 - (-7)

Step-by-step explanation:

The given expression can be simplified:

-(4+(-7)) = -(4-7) = -(-3) = 3

The equivalent choices will all equal 3. Testing each choice:

-4+7 = 3

-4+(-7) = -4-7 = -11

4+(-7) = 4 - 7 = -3

-4 - (-7) = -4 + 7 = 3

Only the first and last choice are equivalent to the original expression.

Answers

Answer:

C) Both (1 , 11) and (-1, -5)

Step-by-step explanation:

y = 8x + 3

Plugin x = 1  and y = 11 in the equation

11 = 8*1 + 3

11 = 8 +3

11 = 11

So, (1 , 11)  is a solution.

Plugin x = -1  and y =-5 ,

-5 = 8*(-1) + 3

-5 = -8 + 3

-5 = -5

So, (-1 , -5) is also a solution
